Anyone heard of this stuff NOT synthetic but a new (dino) racing oil and of course MORE MONEY not that $2.39 a qt. isn`t high enough the "new" stuff is $2.69 ...redvetracr

ps; the drysump IS great but 12 qts at every change (which is every event)

 

No not yet!

and i just bought 2 cases of the old 30w racing........ what's "new" about the new oil? do you know?

 

according the the guy at the parts counter (like he knows!!) the "new" oil doesn`t have some of the additives that made it work with street legal emissions controls like convertors... ...redvetracr

 

What is the API service category? If it's "SL" then it has all the additives that are in typical modern motor oils for spark ignition engines. "Racing oil" typically has a bit more anti-foaming additive.

Why don't you visit the valvoline web site and see what they have to say. Nine buck and hour store clerks are usually clueless about the products they sell.

Duke, as you suggested I went to the web site, now if I can only find a petro-chemical engineer to tell me the difference in ENGLISH!! The "new" racing oil is called conventional oil vs. ZR-1 (the old oil) the differences are, added zinc, friction modifiers, balanced w/reduced detergents.. the conventional race oil is NOT recommended for the street as after time it may damage the converter. Oh yea it is also available at NAPA (which is where I was buying my oil).... ...redvetracr

 

i wonder how much zinc? the VR-1 is .2%. i also see it only comes in 50w (unless you want a multigrade).

 

Unfortunately they don't say if the "new" conventional racing oil is API rated. If it's not "SL" I would not recommend you use it unless you install it just before a track event and then drain it and replace with conventional "SL" oil after the event.

The ZDDP anti-wear additive is believed to degrade catalysts, which is why there is very little in current SL oils. HD diesel engine oils (CI-4) have more ZDDP, and I recommend them for all vintage cars that don't have converters. The CI-4 oils also have higher concentrations of detergents, dispersants, and anti corrosion additives.

The "reduced detergents" also implies that it's not meant for normal length service between oil changes.

Next time you're at NAPA look at the package and see what, if any, API service category rating it has. It may not be rated because of it's specialized use.
